health π©Ί LAA closure only helps high-risk surgery patients
The LAACS-2 trial results showed that routine left atrial appendage closure is not for everyone undergoing open-heart surgery. This study involved 1,500 patients across four sites in Denmark, Spain, and Sweden. Across a median of 4.0 years, there was no overall significant difference in stroke risk between closure and standard care. However, patients with the highest baseline stroke risk saw a 56% reduction in the primary endpoint with LAA closure. Therefore, the benefit is concentrated on those facing major stroke risk. π©Ί
